How Buyers Finance Acquisitions: Debt, Equity, and What It Means for Your Deal

Most founders focus on purchase price and structure when evaluating a buyer's offer. Few spend enough time understanding how the buyer is planning to finance the acquisition, a gap that creates real transaction risk. A buyer's bid is only as good as the financing behind it, and the characteristics of your business directly determine how much financing a lender will approve.

Understanding PE capital stacks and how acquisition financing works is not just useful for founders who want to understand the mechanics. It is directly actionable knowledge: businesses that are structured to be easy to finance attract more aggressive bids, produce more certain closings, and give the seller more leverage in the LOI negotiation.

PE capital stacks: how a leveraged acquisition is financed

A private equity acquisition of a lower middle market company is typically financed with a stack of capital sources: senior secured debt, sometimes a mezzanine or subordinated debt layer, and equity from the PE fund. Each layer of the stack has a different cost, different risk profile, and different impact on the buyer's maximum purchase price.

Senior secured debt is the cheapest and largest component. In the current LMM credit market, senior lenders typically advance 3–5x EBITDA on a solid business, secured by a first lien on company assets. The interest rate is floating (SOFR plus 3–5%), and the term is 5–7 years. Senior lenders look at EBITDA quality, cash flow coverage, asset backing, and management depth when determining how much they will lend.

Mezzanine debt sits between senior debt and equity. It is more expensive (often 10–14% cash interest plus a PIK component or equity kicker) and carries more risk, but it allows buyers to extend leverage beyond what senior lenders will provide. Not all LMM deals include mezzanine; it is more common in the $50M–$150M enterprise value range where the senior debt market alone is insufficient.

Equity from the PE fund covers the balance. If a buyer is acquiring a $35M enterprise value business with 4x EBITDA of senior debt ($20M, assuming $5M EBITDA) and no mezzanine, the equity check is approximately $15M, plus transaction costs and working capital. That $15M comes from the PE fund's committed capital.

How EBITDA quality affects how much buyers can pay

Here is the direct connection between your business's financial characteristics and the price a buyer can offer: the more debt a lender is willing to advance on your business, the more the buyer can pay without writing a larger equity check. Since PE funds have return targets that constrain how much equity they will deploy per deal, senior debt availability is a direct lever on purchase price.

Lenders evaluate EBITDA quality along four dimensions: consistency (EBITDA that fluctuates 30%+ year-over-year is harder to finance than EBITDA that grows steadily 10–15% per year), predictability (recurring revenue or contractual revenue is much preferred over project-based revenue), concentration (a business where three customers represent 60% of revenue will receive less leverage than a diversified business), and management depth (a business that requires the founder to be present post-close is a higher lender risk).

Recurring revenue is the single most important financing characteristic. A business with 80%+ recurring revenue (subscriptions, maintenance contracts, retainers, reorder rates) will consistently get more leverage than a comparable business with project-based or episodic revenue. Lenders model debt service coverage using forward-looking cash flows, and contractual or highly predictable revenue makes those models more supportable.

Customer concentration is the most common financing constraint in LMM deals. If your top customer represents more than 20% of revenue, most senior lenders will haircut the EBITDA assigned to that customer or reduce the advance rate. The practical effect: a $5M EBITDA business where $1.5M of EBITDA is attributable to one customer may effectively be financed as if it generates $3.5M of high-quality EBITDA, reducing the senior debt advance by $4–6M.

SBA 7(a) for smaller LMM transactions

For acquisitions below approximately $5M in purchase price, and in some cases up to $12.35M for businesses that qualify — SBA 7(a) loans are a relevant financing option. The SBA 7(a) program provides government-guaranteed loans to qualified buyers of small businesses, with terms that make lower-price acquisitions more accessible than conventional bank financing alone.

SBA 7(a) key features: loan amounts up to $5M standard limit ($12.35M for certain eligible businesses); 10-year term for business acquisitions; interest rates capped at prime plus 2.75% (well below conventional acquisition financing); and a 10% buyer equity requirement, which means a buyer can acquire a $5M business with $500K of equity (plus the SBA loan proceeds).

For sellers of smaller businesses, SBA financing has important implications. It significantly expands the buyer universe, because many individual buyers and search-fund acquirers who cannot access the PE debt markets can use SBA financing. It also creates different closing dynamics — SBA approvals take 30–90 days and involve the SBA guaranty process, which adds closing timeline risk.

SBA 7(a) lenders apply their own credit standards in addition to the SBA requirements. They evaluate business cash flow, seller discretionary earnings, and the buyer's experience and creditworthiness. For sellers, the practical implication is that pre-qualifying your business for SBA financing (by ensuring clean three-year financials and consistent cash flow documentation) expands the pool of credible buyers.

Financing contingencies in LOIs and how to negotiate them

A financing contingency in an LOI or purchase agreement gives the buyer the right to terminate the deal if they cannot secure financing on acceptable terms. For the seller, a financing contingency is a free put option for the buyer, and they can walk away without consequence if their lender declines the deal.

Sophisticated sellers push for one of three alternatives: no financing contingency (the buyer assumes full financing risk); a defined financing period (the buyer must secure financing within 30–45 days of LOI signing, after which the contingency expires); or a reverse break fee (the buyer pays a termination fee, typically 2–5% of enterprise value; if they fail to close due to financing failure).

A reverse break fee of 3% on a $25M transaction is $750K. That is real compensation for the disruption, time, and opportunity cost of a failed process. PE buyers generally resist reverse break fees, but they are more common in larger transactions and in seller-favorable market environments. The negotiating leverage to extract a reverse break fee typically requires a competitive process with multiple bidders.

How to make your business easier to finance, and more valuable

The improvements that make a business easier for buyers to finance are the same improvements that increase valuation multiples. This is not a coincidence, both effects flow from the same underlying business quality characteristics. Founders who invest in these improvements 12–24 months before a process benefit twice: once in the multiple buyers are willing to pay, and again in the certainty of closing.

Customer concentration remediation: reducing the share of revenue from your top customer from 35% to 18% is a multi-year commercial effort, but the transaction value impact is disproportionate. A business with diversified revenue trades at 0.5–1.5x higher multiples than an equivalent concentrated business, and attracts larger senior debt advances from lenders.

Recurring revenue conversion: if your business currently delivers largely project-based revenue, identifying opportunities to convert episodic customers to retainer or subscription-based arrangements directly improves financing economics. Even a partial conversion, moving 30–40% of revenue to contractual status, materially improves debt capacity calculations.

Management depth: senior lenders care about key-person risk. A business where the CEO and founder is the primary customer relationship holder, the primary operational decision-maker, and the primary institutional knowledge repository is a high-risk lender position. Building a functioning management team with genuine decision authority reduces lender concern and, more importantly, is required for post-close operating continuity.

EBITDA documentation: every legitimate expense addback that is properly documented increases both the EBITDA base and the debt capacity calculation. An undocumented $500K addback that a buyer accepts but a lender skeptically haircuts reduces debt capacity by $1.5M–$2.5M. Clean, well-supported EBITDA documentation is the single highest-ROI pre-process investment in most businesses.
